From 14348aaeff5ccb136e3fe967b86f97b9cea950a2 Mon Sep 17 00:00:00 2001 From: "Gabriel F. T. Gomes" Date: Wed, 7 Dec 2016 16:19:11 -0200 Subject: Make w_log1p type-generic This patch converts the wrapper log1p (which set errno directly rather than doing anything with __kernel_standard) to use the type-generic template machinery, in the same way that has been done for ilogb. Tested for powerpc64le, s390, and x86_64. --- math/Makefile | 5 +++-- math/w_log1p.c | 41 ----------------------------------------- math/w_log1p_template.c | 36 ++++++++++++++++++++++++++++++++++++ math/w_log1pf.c | 36 ------------------------------------ math/w_log1pl.c | 36 ------------------------------------ 5 files changed, 39 insertions(+), 115 deletions(-) delete mode 100644 math/w_log1p.c create mode 100644 math/w_log1p_template.c delete mode 100644 math/w_log1pf.c delete mode 100644 math/w_log1pl.c (limited to 'math') diff --git a/math/Makefile b/math/Makefile index b5d498819c..1e96100120 100644 --- a/math/Makefile +++ b/math/Makefile @@ -52,7 +52,8 @@ gen-libm-calls = cargF conjF cimagF crealF cabsF s_cacosF \ k_casinhF s_csinhF k_casinhF s_csinhF s_catanhF s_catanF \ s_ctanF s_ctanhF s_cexpF s_clogF s_cprojF s_csqrtF \ s_cpowF s_clog10F s_fdimF s_nextdownF s_fmaxF s_fminF \ - s_nanF s_iseqsigF s_canonicalizeF w_ilogbF w_llogbF + s_nanF s_iseqsigF s_canonicalizeF w_ilogbF w_llogbF \ + w_log1pF libm-calls = \ e_acosF e_acoshF e_asinF e_atan2F e_atanhF e_coshF e_expF e_fmodF \ @@ -61,7 +62,7 @@ libm-calls = \ e_ilogbF \ k_cosF k_sinF k_tanF s_asinhF s_atanF s_cbrtF \ s_ceilF s_cosF s_erfF s_expm1F s_fabsF \ - s_floorF s_log1pF w_log1pF s_logbF \ + s_floorF s_log1pF s_logbF \ s_nextafterF s_nexttowardF s_rintF s_scalblnF w_scalblnF \ s_significandF s_sinF s_tanF s_tanhF w_acosF w_acoshF w_asinF \ w_atan2F w_atanhF w_coshF w_expF w_exp2F w_exp10F w_fmodF \ diff --git a/math/w_log1p.c b/math/w_log1p.c deleted file mode 100644 index 282c85cb5c..0000000000 --- a/math/w_log1p.c +++ /dev/null @@ -1,41 +0,0 @@ -/* Wrapper for __log1p that handles setting errno. - Copyright (C) 2015-2016 Free Software Foundation, Inc. - This file is part of the GNU C Library. - - The GNU C Library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - The GNU C Library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
